Group V Element Heterocycles

Oxirene (2) is one of a number of heterocycles in which the CH2 group of cyclopropene has been replaced by a group or element associated with Groups V or VI of the periodic table. Replacement of the CHj group of cyclopropene by an NH group gives l//-azirine... [Pg.120]

Heterocycles with elements of group V are known too, chiefly with nitrogen. Only a few compounds with phosphorus have been described. Nonaphenyl-phosphocyclopentasilane is formed by the reaction described above256) ... [Pg.87]

An alternative concept for the deposition of III-V material films, the so-called single-source precursor concept, was introduced by Cowley, Jones and others almost 15 years ago [10]. Typical group 13/15 single-source precursors such as Lewis acid-base adducts R3M - ER 3 or heterocycles [R2MER 2]% as shown in Scheme 1 contain the specific elements of the desired material connected by a stable chemical bond in a single molecule. [Pg.103]
